Micro800 Plug-in Modules Chapter 1
Digital Plug-ins
12/24V Digital Plug-ins — 2080-IQ4, 2080-IQ4OB4, 2080-IQ4OV4,
2080-OB4, 2080-OV4
These digital plug-in modules provide transistor outputs for switching a variety
of 12/24V DC voltages to field loads and for detecting 12/24V signals from field
devices.
AC/DC Relay Output Module — 2080-OW4I
The 2080-OW4I is a 4-channel relay output and provides dry contact relay
closure outputs for switching a variety of AC and DC voltages to field loads.
Analog Plug-ins
The following analog plug-ins are supported by most Micro800 controllers.
Non-isolated Unipolar Analog Input and Output — 2080-IF2,
2080-IF4, 2080-OF2
These plug-in modules add extra embedded non-isolated unipolar (0...10V,
0...20 mA) analog I/O and offer 12-bit resolution.
Specialty Plug-ins
Non-isolated Thermocouple and RTD — 2080-TC2 and 2080-RTD2
These non-isolated plug-in modules help to make temperature control possible
when used with PID (Proportional Integral Derivative).
See Non-isolated Thermocouple and RTD Plug-in Modules – 2080-TC2 and
2080-RTD2 on page 19 for more information.
Memory Backup and High Accuracy RTC — 2080-MEMBAK-RTC
and 2080-MEMBAK-RTC2
These plug-in modules allows you to make a backup copy of the project in your
controller, and adds precision real-time clock function without needing to
calibrate or update periodically.
They can also be used to clone/update Micro800 application code. The
2080-MEMBAK-RTC2 has larger memory to support clone/update for
Micro870 application code. However, these plug-in modules cannot be used as
additional Run-Time Program or Data Storage for recipe and datalog.
